How long will the batteries last?

Unfortunately, there is no easy answer regarding the life of a battery because there are many variables which affect battery performance, including:

  • the type of speech processor;
  • the type of battery used: rechargeable or zinc-air;
  • the brand of battery used;
  • the map and volume settings;
  • how many hours per day you use your cochlear implant;
  • the amount and type of environmental noise;
  • the level of humidity; and
  • how you store the batteries.

Most of our customers who use the Nucleus Freedom speech processor report getting about 3 days out of the batteries.

If you are not using your speech processor for a few weeks, we recommend removing the battery to minimise the risk of damage from battery leaks or corrosion.
